BOM TCodes in SAP: Complete Guide with Descriptions

The Bill of Materials is SAP's main master data structure that specifies the components, amounts and their association that are needed for the assembly, maintenance, service and production of a product. Because Bill of Materials data are able to influence production planning, procurement, inventory, costing, maintenance, the BOM needs to be maintained correctly.

SAP provides transaction codes, or TCodes, for creating, changing, displaying, comparing, reporting, and analyzing BOMs. In this guide, you will learn the most useful SAP BOM TCodes, their purposes, and their applications across different BOM processes.

It covers common material BOM transactions such as CS01, CS02, CS03, CS11, CS12, CS13, CS14, CS15, and CS20, along with specialized BOM transactions. Exact availability and functionality can vary according to SAP release, configuration, and user authorization.

What Is a BOM in SAP?

A Bill of Materials is a structured listing of the materials or parts that make up a product or assembly (product structure). SAP Bills of Materials typically lists component item quantities, units of measure and defines the relationship between the header product/assembly and the individual components needed to build the product/assembly.

For example: If the BOM’s structure is for a finished machine it could comprise different assemblies, raw materials and hardware (screws, bolts, etc). These structures are often used in planning material needs, managing the production process, purchasing, costing and maintenance.

SAP supports different BOM categories, including material BOMs, equipment BOMs, functional location BOMs, standard BOMs, order BOMs, and WBS BOMs. The exact BOM type used depends on the business process and SAP configuration.

What Are BOM TCodes in SAP?

SAP TCodes are short codes which can be used directly for accessing an SAP function. The BOM TCode in SAP helps you to do a particular task on BOM without following various menu paths.

The correct TCode depends on the task. CS01 is used to create a material BOM, CS02 to change it, and CS03 to display it. Other transactions support BOM reporting, comparison, where-used analysis, mass changes, and specialized BOM types.

The knowledge of TCodes will enable a fast working SAP but it is also necessary to know the underlying business need of each transaction code. It is much more useful to know the requirements and effects of each transaction than to learn all the Tcodes.

Complete SAP BOM TCodes List with Descriptions

The table below provides a consolidated reference of important BOM-related TCodes.

Some specialized or legacy transactions may vary by SAP release and configuration. The users must check their availability in the targeted SAP system. For the learners who wish to relate these codes to real-world manufacturing situations, the SAP BOM course will be beneficial for them.

Most Commonly Used SAP BOM TCodes

Although the complete list is extensive, a few transactions are especially important for daily material BOM activities.

CS01, CS02, and CS03 are the most important starting points for beginners because they cover the basic create, change, and display cycle.

SAP BOM TCodes for Creating, Changing and Displaying BOMs

The basic material BOM maintenance process uses three primary transactions.

CS01 is used to create a material BOM. Depending on the configuration, users enter information such as material, plant, BOM usage, base quantity, components, and quantities.

CS02 is used to modify an existing BOM. Changes may include adding or removing components, changing quantities, or maintaining other BOM information. Because BOM changes can affect planning and production, access is generally restricted to authorized users.

CS03 is used to review a material BOM without making changes.

An easy way to remember them is:

• CS01 = Create

• CS02 = Change

• CS03 = Display

SAP BOM TCodes for BOM Reporting and Analysis

Reporting and analysis transactions help users understand product structures and component relationships.

CS11 and CS12 help users examine multilevel product structures, while CS13 provides summarized information. CS14 is useful for identifying differences between BOM structures.

CS15 is particularly valuable for where-used analysis. If a component is discontinued, replaced, redesigned, or affected by a quality issue, users can identify the BOMs in which that component is used. Specialized systems may also provide transactions for order and WBS BOM analysis, depending on the SAP release and implementation.

How to Use SAP BOM TCodes

Effective use of BOM TCode is initiated through recognition of the business activity that one requires. One needs to know if he wants to create, update, display, compare or analyze the BOM before choosing the transaction.

Step 1: Identify the material, plant, or BOM object

Step one is to find out the material, plant, or BOM object that you will be dealing with. The accuracy of the data is important.

Step 2: Determine the required activity

Choose how you want to work with the BOM. This may involve creation of a BOM, modification of a BOM, viewing information about BOMs, structure comparison or analysis.

Step 3: Select the appropriate TCode

Choose the SAP transaction code that matches your requirement. For example, use CS01 to create a material BOM, CS02 to change one, and CS03 to display one.

Step 4: Enter the required information

Enter the necessary details, such as the material number, plant, BOM usage, components, quantities, and other fields required by your SAP system.

Step 5: Review the BOM details

Before saving, carefully review the components, quantities, units of measure, and overall BOM structure to ensure the information is accurate.

Step 6: Save changes only when authorized

If you are making changes, save the BOM only if you have the required authorization. Changes to BOM master data can affect production planning, procurement, costing, and manufacturing activities.

Step 7: Verify the BOM

After creating or changing the BOM, verify the final structure to ensure that the required components and quantities have been maintained correctly.

For example, CS01 is suitable for creating a material BOM, while CS03 is appropriate for reviewing one. Before using CS02, users should understand how the change could affect production planning, procurement, costing, or manufacturing.

Plant, BOM usage, validity dates, alternatives, and authorization should also be checked. Practicing TCodes in a training or sandbox environment is recommended before working with live production data.

SAP BOM TCodes by SAP Module

BOM information can interact with several SAP areas depending on the organization's processes.

SAP PP has a particularly strong relationship with BOMs because BOM data supports production planning and manufacturing. Other modules may use related BOM information according to business requirements.

Conclusion

Understanding SAP BOM TCodes helps professionals manage product structures more efficiently. CS01, CS02, and CS03 provide the foundation for creating, changing, and displaying material BOMs, while CS11, CS12, CS13, CS14, and CS15 support structure analysis, comparison, summaries, and where-used activities.

SAP also provides specialized transactions for different BOM categories and processes. However, knowing only TCodes is not sufficient. Master Data, Business Processes, Authorizations, Validity, and the effects of any change made on subsequent transactions need to be known for effective BOM Management.

Transaction behavior may vary depending upon the release and configuration of SAP. Therefore, it is advised to verify the transaction in your own SAP environment. Want to gain hands-on SAP experience? Check out the SAP training courses offered by Srijan Institute.
